Riverwood High School in Sandy Springs was locked down Wednesday afternoon after a “very general bomb threat” was picked up on social media, police said.

Law enforcement responded to the school and found nothing.

Channel 2 Action News reported the threat was sent through a program called Yik Yak. The app allows users to share and view a wall of anonymous posts about anything from people nearby.

The school at 5900 Heards Drive, N.W., is no longer locked down.
